My advice is to find a local mtb clinic or skills course if you can. Even if you have to travel a bit to find one, I think it's worth it. Certainly, some learn just fine from a significant other, but if your experience ends up being like mine, it can turn pretty tense, too. My husband "knows" how to mountain bike, but that doesn't mean he can break down the skills for a new rider or is otherwise using the best technique. And certainly, some people are self taught, but that road is often paved in needless frustration and injury. The best way to learn, IMO, is from a trained instructor. Even if all you cover the basics, they'll get you headed in the right direction.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
